我有一些 lat,lng 坐标,用于绘制来自数据库的折线。我使用 asp.net c# 和 sql server。下面来自gmaps的示例代码,它在 html 端有路径作为字符串。我如何从后面的代码调用/写入 db 中的 lat,lngs 到这里?它是如何工作的?
<script type="text/javascript">
var map;
$(document).ready(function(){
map = new GMaps({
el: '#map',
lat: -12.043333,
lng: -77.028333,
click: function(e){
console.log(e);
}
});
path = [[-12.044012922866312, -77.02470665341184], [-12.05449279282314, -77.03024273281858], [-12.055122327623378, -77.03039293652341], [-12.075917129727586, -77.02764635449216], [-12.07635776902266, -77.02792530422971], [-12.076819390363665, -77.02893381481931], [-12.088527520066453, -77.0241058385925], [-12.090814532191756, -77.02271108990476]];
map.drawPolyline({
path: path,
strokeColor: '#131540',
strokeOpacity: 0.6,
strokeWeight: 6
});
});
</script>
